No. 123,316 Claims priority, application France July 21, 1960 1 Claim. (Cl. 172234) The present invention relates to a mechanical control system for the inward rocking of the independent shares of a plough removing spoil heaps in vineyards.

It is one object of the present invention to provide a mechanical control system for the inward rocking of the independent shares of a plough removing spoil heaps in vineyards, which spoil heaps surround the vinestock roots, and wherein the plough has on either side of the plough beam two independent shares which are adapted to remove the spoil heaps and the operative breadth of the plough beam is adjustable and which are capable of operating in two adjacent rows of vine plants simultaneously, while two feeler projections carried by the shares abut the successive vine roots and cause an inward rocking of the shares during the passage of the plough beyond the vinestocks.

It is another object of the present invention to provide a mechanical control system for the inward rocking of the independent shares of a plough removing spoil heaps in vineyards, which includes a purely mechanical system for rocking inwardly each of the two independent shares which in turn remove the spoil heaps.

It is yet another object of the present invention to provide a mechanical control system for the inward rocking of the independent shares of a plough removing spoil heaps in vineyards, wherein each of the two shares is rockably mounted and is secured through a pivotal connection of a so-called silent-block or rubber block type to the end of an arm pivoting about a pivot secured to a lug formed on a cam member the face of which may be engaged and followed by an auxiliary projection integral with the end of the feeler projection. The latter is normally directed outwardly by a further rubber or silent-block fitted on a pivot mounted in its turn on a lug rigid with said pivoting arm. This arrangement ensures, by means of a rearward rocking of the feeler projection abutting against a vine root and in opposition to the action of the two silent-blocks, the pivotal inward movement of the shares carried at the ends of the pivoting arms and the rocking of the share jointly with an inwardly shifted pivot which is carried adjustably by the cam member. The latter is carried by a bar means, the ends of which are secured to two stationary points, so as to form one side of a deformable system ensuring in a conventional manner the adjustment of the operative breadth between the independent shares.

With these and other objects in view, which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

FIGURE 1 is a diagrammatic top plan view of the plough; and

FIG. 2 is a section taken along the lines 2-2 of FIG. 1.

Referring now to the drawing, two shares 1 are provided, adapted to remove spoil heaps, each of the shares being fitted on a bar 2 pivotally secured at 2 to the end of an arm 3, which in turn is pivotally secured to a lug 4 on a bar member 5 which is included in a bar means 6.

The bar means 6 carries pivotally, on the one hand, a link 9 pivotally secured to a transverse beam 10 common to the two shares 1 and, on the other hand, another link 11 forming with a further link 12 a bent lever pivotally secured to a stationary point 13 of'the plough frame, the point 13 registering with the point of connection between the links 11 and 12.

A feeler projection 7, the free end of which is bent rearwardly, is pivotally secured to a lug of the pivoting arm by means of a pivot 8.

A link 14 is pivotally secured at one end to the bent lever 11, 12 while its other end is secured pivotally to a lug provided on a nut 15 screwed to a threaded rod 16 which is rotatable by means of a hand wheel 17; the rotation of the hand wheel 17 ensures upon shifting of the nut 15, a pivoting movement in either direction of the bent lever 11, 12. This produces a deformation of the system consisting of the members 6, 9, 10 and 11 and the rocking of the supporting bar means 6 brings about the result that that the plough beam is shifted apart from or moved nearer to the members 5 and also members 23 integral with the bar means 6. The members 23 are provided with holes 22 selectively engageable with a rod 21 which is pivotally secured at the pivot 20 to the apex of a non-deformable triangle 2*, the base of which is the bar 2 to which the operative share 1 is secured.

To the end of the feeler projection 7 and in the immediate proximity of its pivotal connection with the lug of the pivoting arm 3 is secured a small projection 18 adapted, upon rotation of the feeler projection, to engage the face of a cam 19 integral with the member 5 of the the bar means 6 and then to slide over the face, so as to engage and to shift the pivotal connection 8 and, thereby to rock the pivoting arm 3 inwardly, which shifts the pivotal point 2' inwardly and causes the share 1 to rock about the pivot 2'.

Each of the pivots 8 and 2 is designed as an elastic pivot of the so-called silent-block type (FIG. 2), and comprises a rubber bolt 2" and 8', respectively.

It should be remarked that the pivotal connection of the feeler projection 7 is provided on a lug 8" integral with the pivoting arm 3 and not on the actual arm, so as to further the movement of the small projection 18 which should move beyond an idle point before it exerts a thrust which produces the slight pivotal movement of the arm 3. Furthermore, the pivot 20 forms a rocking hinge for the share 1 and may be slightly shifted through the engagement of the rod 21 with another hole in the member 23, so as to correct the conventional adjustment of the spacing between the axis of the plough and the pivot 4 for the pivoting arm 3 and, thereby, for the share 1.

Obviously, the lengths of the various members providing the mechanical control of the receding motion of the shares 1 are adjusted in a manner such that the receding motion produced by the feeler projection 7 at the moment at which it abuts against a vinestock is obtained just at the moment at which the share 1 reaches the immediate proximity of the vinestock, while the rubber bolts 2" and 8 included in the pivot 8 of the feeler projection 7 and in the pivot 2 of the arm, respectively, return automatically the share 1 and the feeler projection 7 into their original positions immediately after they have passed beyond the vinestock.

While I have disclosed one embodiment of the present invention, it is to be understood that this embodiment is given by example only and not in a limiting sense, the scope of the present invention being determined by the objects and the claim.
